SPICE-VALVE FOR COBNETS.

To all whom it may concern Be it known that I, FRANK A. SNYDER, acitizen of the United States, residing at Pittsburgh, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulSpit-Valve for Cornets; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to the art of musical instruments, andparticularly to brass and other wind instruments; and the object of theinvention is to provide an improved spit valve or water key for use inconnection with a cornet or the like.

Another object of the invention is to provide a water key of such aconstruction as to eliminate the use of forks and springs, which arecommonly used in connection with water keys.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a plan view of a cornet showing theimproved water or spit valve as applied thereto. Fig. 2 is an enlargeddetail View of a portion of the cornet showing the water key. Fig. 3 isa sectional view longitudinally through the water key. Fig. A is atransverse sectional view.

Referring more especially to the drawings, 1 designates a wind musicalinstrument, which may be a comet, trombone or the like, and soldered orotherwise fastened to the curved portion 2 of the instrument is anarched plate 3, with which an elongated plate 4 forms an integral part.The side portions of the plate 4 are provided with longitudinal guidesor grooves 6 formed in the flanges 7. Movable longitudinally in theguides is a valve plate 8 provided with an opening 9 to register withthe opening 10 in the plate 4. This opening 9 has an adjacent thimble11, and when the valve plate 8 is adjusted so that the opening 9registers with the opening 10 of the plate 4, the water or spittle inthe instrument will exit freely. Projecting from the flanges 7substantially centrally between the ends of the plate 4 andSpecification of Letters Patent.

arranged diametrically opposite are lugs 12, which constitute abutmentsto be engaged by the thimble of the valve plate, to limit the same inposition, when the openings 9 and 10 register. A thumb or finger piece13 18 provided having a screw threaded lug 14L threaded into a smallopening 15 of the valve plate. When the valve plate is adjusted so thatthe openings 9 and 10 are out of registration, the finger or thumb piececontacts with the lugs 12, thereby limiting the valve plate in suchposition. The plate 4 is constructed of brass or other suitable metalcorresponding to the metal of the wind instrument, while the valve plate8 is designed to be constructed of steel and machined so as to beperfectly even and smooth, so as to closely fit the guides or groovesand against the surface of the plate 4. As the valve plate 1s moved inone direction to register the openings 9 and 10, the thimble abutsagainst the lugs, and when moved in the opposite direction, throwing theopenings 9 and 10 out of registration, the finger or thumb piececontacts with said lugs.

The invention having been set forth, what is claimed as new and usefulis 1. In combination with a wind musical instrument having a water exitopening, a plate having guides secured to the instrument and providedwith an opening registering with the opening of the instrument, a slidevalve plate mounted in said guide and provided with a thimbled openingadapted to be thrown in and out of registration with the first opening,said valve plate having a thumb piece at its end opposite the thimbled.opening, and means projecting from the guides between the thimble of theopening and the thumb piece, to limit the valve plat in its movement ineither direction. A

2. In combination with a musical wind instrument having a water exitopening and provided with diametrically opposite elongated guides, apair of lugs extending from the guides toward one another and arrangeddiametrically opposite each other, a slide valve plate mounted in theguides provided with an opening at one end and an adjoining thimble, andwith a thumb piece at the other end, the thimble adapted to contact withthe lugs to limit said valve plate when moved in name to thisspecification in the presence of one direction to cause said openings toregister, Whereas the thumb piece contacts with said lugs to limit thevalve plate when moved in the opposite direction with the openings outof registration.

In testimony whereof I have signed my two subscribing Witnesses.
